There is not one but there are two metalloids in Period 4 of the Periodic Table. They are germanium and arsenic. There is a link below to the Wikipedia post on the metalloids so you can have a look at them.
There are 4 electronic shells in period 4 while there are 5 shells in period 5.Elements of period 4 are smaller in size as compared to elements of period 5.Example of period 4 element is potassium and period 5 element is tin.
There are 18 elements in period 4 of the periodic table, corresponding to 4 shells.
The metalloid in period 2 of the periodic table that is part of compounds used in softeners is Boron.
The elements H (Hydrogen) and He (Helium) are in the first period, Ge (Germanium) is in the fourth period, Rb (Rubidium) is in the fifth period, and I (Iodine) is in the fifth period.
Manganese is in the fourth period of the Periodic Table of Elements. Periods are rows, groups are columns within the Periodic Table of Elements.
There are several metaloids and each has a different number of electrons than the others metaloid elements have.
There are 4 electronic shells in period 4 while there are 5 shells in period 5.Elements of period 4 are smaller in size as compared to elements of period 5.Example of period 4 element is potassium and period 5 element is tin.
There are 18 elements in period 4.
Period 1: 2 elements Period 2: 8 elements Period 3: 8 elements Period 4: 18 elements Period 5: 18 elements Period 6: 32 elements Period 7: 25 elements
metaloid and metal
The period 4 representative elements are: K, Ca, Ga, Ge, As, Se, Br, Kr.
Period 4 and period 5 of the periodic table have the same number of elements. There are 18 elements in each period. While some elements in period 4 are calcium, iron, and zinc, elements in period 5 are tin, antimony, and iodine.
There are 18 elements in period 4 of the periodic table, corresponding to 4 shells.
Group 4 elements on the periodic table contain no period 2 elements whatsoever.
A metaloid will generally have a very high melting point.
The fourth period contains 18 elements beginning with potassium and ending with krypton – one element for each of the eighteen groups. It sees the first appearance of d-block (which includes transition metals) in the table. Do You Agree? Sincerely, Jocelyn E.Flowers
The metalloid in period 2 of the periodic table that is part of compounds used in softeners is Boron.
